Warning and Mitigation Technologies for Travelling Ionospheric Disturbances Effects


Report on the scales indicating the severity of TID effects in EGNOS, N-RTK and HF communication and geolocation

The report specifies (a) under which conditions (driven by solar wind-magnetosphere coupling level and by the lower atmosphere) the systems under investigation are more vulnerable to TID activity; (b) under which geospace and atmospheric dynamic conditions, the results from the TID detection methods can support more efficiently specific types of operations.

TechTIDE Dissemination, Exploitation & Communication strategy

The reports presents the final strategy for the dissemination, exploitation & communication activities, refined based on the feedback received from TechTIDE stakeholders and potential users and considering the latest developments in the field.

Communication results final report

The report provides an overview of the communication results targeted to aware the public about the impacts of Space Weather on systems using the ionosphere for its operations.

Report on the design of the mitigation procedures and implementation schedule

The report identifies potential mitigation actions using TechTIDE products and selects mitigation actions based on final user’s needs, focusing on the three types of operational systems, i.e., EGNOS, HF communications and N-RTK. The design and implementation schedule for the identified mitigation procedures are presented in this deliverable.

Report on the TechTIDE workshops and the final meeting

The report summarizes the main conclusions from the two TechTIDE workshops and the final project meeting, and provide access to the key presentations delivered by the TechTIDE members, the users and the stakeholders.

Final Public Report

The report summarizes the main achievements of TechTIDE project.

Report on TID activity metrics definition

The deliverable presents the TID activity report. It will contain results from the TID detection methods, the additional geophysical information for overall assessment of current conditions, and the classification of the TID activity. Statistical limits will be specified based on which, the TID disturbance will be characterized as unimportant, weak, moderate and intense.

Dissemination results

The report presents an overview of the dissemination activities and evaluates the results in respect to the key performance indicators.

Report on methodology for the specification of additional parameters

This report presents the methodology for the specification of (a) TID drivers (b) ionospheric background conditions (c) interhemispheric circulation.

Report on TID drivers

The report presents results from (a) the analysis of the magnetospheric response during isolated substorms, CME and CIR/HSS-related events to identify LSTID drivers; (b) the analysis of data from ARISE data center (atmospheric dynamics and infrasound signatures of natural and anthropogenic sources) compared with results from the CDSS network to identify MSTID drivers.

Methodology for the identification of the interhemispheric circulation

The report presents results from case studies in order to prepare future systematic and comprehensive investigations of conjugate excitation of TIDs in both hemispheres, their subsequent propagation to the opposite hemisphere, and their interaction in the vicinity of the geomagnetic equator. These studies exploit temporally coincident observations, spanning all seasons, from similar ground-based facilities (Digisondes, HF Doppler systems, GNSS networks) located in Europe and Africa, i.e., in the same longitude sector.

User manual

The user manual will provide full guidance on the functionalities of the TechTIDE prototype, presenting specific examples, and summarising the answers to the questions most frequently received through the Users' Support Center.

Final users' requirements report

The final users’ requirements will build on the initial users’ requirements (D1.1) and will be adjusted based on the project developments and interaction with the users. Specifically, D1.3 will exploit by results from Task 6.2 “Development of mitigation procedures”, and Task 7.4 “Networking with users and stakeholders”, and the compiled information will be documented in an updated Users’ Requirements report.

Initial users' requirement report

The TechTIDE partners with good connections with the operations sector, will collect users’ requirements. The collected requirements will be categorised, prioritised, evaluated including their realism and feasibility and compiled into a report.

Exploitation results

Key Performance Indicators

The report specifies the key performance indictors to measure and monitor the impact of TechTIDE in all project’s phases.

Models for the specification of ionospheric background

The precise identification of TIDs requires accurate determination of the background conditions that define the level of the ambient electron density. The report presents new algorithms for the calculation of the ambient electron density and the corresponding values of MUF, TEC and foF2 through systematic assessment of several state of the art methodologies.

Report on Operation of mitigation procedures

Warning system Requirements report

The warning system requirements are driven by the users' initial requirements (D1.1 and by the community standards. In this report we will collect requirements based on the participants experience from the operation of ionospheric specification and Space Weather prediction systems (NOA/DIAS, NOA/NetTIDE, DLR/SWACI), from the development of Space Weather services for the ESA SSA Programme and the coordination of the Ionospheric Expert Service Center (DLR) and from the development of large e-infrastructure projects (NOA as a scientific manager of the ESPAS).

TechTIDE warning system specifications

The report will provide the specifications of the TechTIDE warning system, driven from WP1 (users' requirements and system requirements), WP2 (design of algorithms development and upgrades), WP3 (Design of additional parameters required for the TID activity report). The system will be powered by open source software for OS, web sites, data interfaces, databases, registries and usage monitoring, while specific effort will be devoted to define the interoperability requirements between TechTIDE and the service and data providers.

Report on the final TechTIDE products

Driven by WP5 (Assessment of the TID impact on aerospace and ground systems) results, the TID identification codes will be adjusted to efficient support specific systems operations (such EGNOS, N-RTK, HF communication and geolocation) and the mitigation of the TID effects. The final TechTIDE products released after this adjustment, are described in this report.

Report on the design and specifications of the TID algorithms and products

The deliverable will report on the design of the adjustments and upgrades required in order to develop the TID identification algorithms. The added value products that will result from the detection methods will be specified and designed. Each detection method developer will design a validation methodology that will lead to the definition of the confidence metrics.
